Product description

Motor Grader

  • ENGINE POWER:With 160kW/2200, this engine conforms to China-II non-road machinery emission regulation
  • OVERALL WEIGHT:16800kg
  • WIDTH OF SHOVEL BLADE:3660/3965/4270mm

CHARACTERISTIC

  • Power System

    ● It's powered by Dongfeng Cummins 6CTAA8.3-C215 China-II compliant inline, 4-stroke, direct injection, water-cooled, and turbocharged and intercooled diesel engine, featuring compact structure, stable performances, and high efficiency and energy-saving.

    ● The high torque reserve enables the machine to output stable power under severe working conditions and meet your working needs.

  • Driving/Riding Environment

    ● The high-grade full-sealed luxury cab with full visual field and the high-efficiency shock-absorbing seat maximize the operating comfort.

    ● The cab and the main frame are connected by shock absorber to ensure the operating safety and reliability.

  • Working adaptability

    ● With 6 forward gears and 3 reverse gears, the electro-hydraulically controlled power shift transmission can select the optimal gear based on the working road condition to realize the best match between traveling and operation.

    ● The integral three-segment drive axle is built internally with imported no-spin automatic limited slip differential to guarantee stable and reliable drive. 

    ● The balance box is capable of 15° angular swing in vertical direction and the heavy-duty roller chain drive guarantees better terrain adaptability of the machine. It can meet the normal operations under special road conditions, featuring stable power output and strong drive force.

  • Operating performance

    ● It features the highest traction force among the domestic motor graders of like type and the highest operating efficiency among the domestic products of like type.

    ● The external gear working device of proprietary technology features high drive torque and strong resistance against external force impact.

    ● The blade of larger angular adjustment range (37°-83°) improves the material control capability and remarkably promotes the operating efficiency of motor grader, especially during the handling of dry material and clay.

    ● With full-load scraping capability in 2nd forward gear, the motor grader can remarkably promote the production efficiency compared with domestic products of like type.

    ● With high resistance against external force impact, the link type swing frame is applicable for the working conditions with high operating volume and severe operating environment.

  • Easy maintenances

    ● The hydraulic pin puller cylinder can complete the operations of swing frame by merely one operator to eliminate all potential safety hazards and ease user’s operations.

    ● The structural parts inherit the excellent quality of Shantui mature products.

    ● The electric harnesses adopt seamless corrugated pipes and deconcentrators for branching, featuring high protection grade.

    ● The maintenance-free battery installed on the rear of the machine features high power capacity.

    ● The core electric and hydraulic parts adopt imported products, featuring stable and reliable quality and extremely high reliability.
